Iibholiti ezinemibala ye-zinc: ukuveliswa kwezinto ezintsha? 

Ubona 'iibholiti ezinemibala ye-zinc' kwiphepha elithile okanye iwebhusayithi yomthengisi, kwaye ukusabela kwangoko kwizinto ezininzi zokuthenga okanye zobunjineli kukukrokra. Ngaba ligimmick nje lokuthengisa? Indlela yokuhlawula i-premium ye-fastener eqhelekileyo kunye nentwana yedayi kwindawo yokuhlambela? Ndibe ndikwindawo ekhawulezayo yokukhangela kunye nesicelo ixesha elide ngokwaneleyo ukuba ndibenokwabelana ngokugxeka. Ukutsiba ekuyiboneni njenge-aesthetics ecocekileyo ukuya ekuyiqondeni njengento enokwenzeka, nangona i-nuanced, Ukuveliswa okuzinzileyo ifuna ukugrumba kwinkqubo yokwenyani, ukusilela, kunye norhwebo lwehlabathi lokwenyani ukuba amaphepha angaze akuxelele.

Umbono ongeyiyo: Yipeyinti nje

Umqobo omkhulu yingcinga yokuba umbala yingubo engaphezulu, njengepeyinti yokutshiza. Oko kuya kuba yintlekele yokumelana nokubola kunye nokunyamezela intambo. Inkqubo esithetha ngayo I-chinc ye-zinc ye-zinc, ngokukodwa i-post-plating chromate conversion coating apho idayi idityanisiwe. Ibholithi ifumana umaleko wayo oqhelekileyo we-zinc wokukhusela idini, emva koko ihlanjwe ngekhemikhali passivation bath. Kukulo bhafu apho iityuwa zetsimbi zenza umaleko onzima, kwaye idayi ephilayo inokuthi ifakwe kuloo matrix. Umbala awuhlali phezulu; yinxalenye yomaleko othintela ukubola ngokwawo.

Ndikhumbula iprojekthi kwiminyaka edlulileyo yombane wangaphandle. Umzobi wayefuna iibholithi ezimnyama zihambelane nomdlalo, kwaye iqela labalungisayo lanyanzelisa ukuba kufakwe amazinki ukuze kudle umhlwa. Unokontraka, ezama ukonga ixesha, wasebenzisa iibholiti zegalvanized eziqhelekileyo kwaye wazipeyinta zaba mnyama kwindawo leyo. Kwisithuba nje seenyanga ezili-18, saphinda safowunelwa kwiziqhoboshi ezithimbileyo. Ipeyinti echotshiweyo ekufakeni, ukudala i-micro-gaps, ukufuma kungene ngaphantsi, kwaye i-zinc ayikwazanga ukwenza umsebenzi wayo ngokufanelekileyo. Yayiyimeko yakudala yokusombulula umbala ngendlela engalunganga, ijongela phantsi umsebenzi wokuqala.

Kulapho inkqubo efanelekileyo ye-zinc enemibala ibonisa ixabiso layo lokuqala elisebenzayo: idibanisa ikhowudi yombala okanye ukuhambelana kobuhle kunye nokugcinwa, kwaye ngamanye amaxesha kuphuculwe, ukusebenza kwe-corrosion. Umaleko wechromate, nokuba ucacile, umthubi, umnyama, okanye uluhlaza, wongeza umqobo owongezelelweyo. Ke into entsha ayingombala ngokwesese; luhlanganiso ngaphandle kokuthomalalisa ukusebenza.

I-engile yoZinzo: Ngaphezulu kokudibana neso

Xa sithetha ngokuzinza kwii-fasteners, ngokuqhelekileyo malunga nezinto eziphathekayo (intsimbi ehlaziyiweyo) okanye iinkqubo zokugubungela (ukunciphisa i-chromium ene-hexavalent). I iibholiti ezinemibala ye-zinc i-engile ifihlakeleyo. Cinga ngolawulo lwee-asethi kumzi-mveliso omkhulu okanye iplanti eluncedo. Uneemayile zemibhobho, iinkqubo ezahlukeneyo (amanzi, igesi, imigca yeekhemikhali), zonke zibanjwe kunye namawaka eebholithi. Ukuba ibholithi nganye yizinki yesilivere, ukuchongwa ukuze kugcinwe, kuhlolwe, okanye kufakwe enye endaweni yayo kuliphupha elibi. Uthembele kwiithegi eziphelileyo okanye kwimemori.

Ngoku, cacisa iibholithi eziluhlaza okwesibhakabhaka kwimigca yamanzi aselwayo, ebomvu yoxinzelelo oluphezulu lwe-steam, eluhlaza kukhuseleko lwe-anchor points. Ngokukhawuleza, ulawulo olubonakalayo lungaphakathi. Oku kunciphisa iimpazamo ngexesha lokulungiswa. Igcisa aliyi kuyisusa ngempazamo ibholithi yesakhiwo ecinga ukuba yeyombhobho ongabalulekanga. Oku kwandisa ubomi be-asethi, kuthintela ukutshintshwa ngokungeyomfuneko, kwaye kunciphisa umjikelo wokukhupha kunye nokulahla. Leyo yinto ebonakalayo, nangona ihlala ingahoywa, inzuzo ezinzileyo-ukunciphisa inkunkuma ngokuphucula ubomi obude kunye nokuchaneka.

Kukwakho nomba we-chromium onehexavalent. Ukugqitywa kwe-zinc eqaqambileyo yemveli ihlala isebenzisa i-chromate enehexavalent, elawulwa kakhulu (RoHS, REACH). Iinkqubo ezinemibala, ngakumbi i-shades emnyama kunye nezinye ezimnyama, zihlala zisebenzisa ii-trivalent chromate ezinye iindlela zokufezekisa i-hue. I-Trivalent chrome ayinabungozi kangako kwaye inobungozi kokusingqongileyo. Ke, ukucacisa umbala ngamanye amaxesha kunokuba yindlela yokuchasa kancinci ukuhambisa iprojekthi ukuya kwindawo ehambelanayo nendalo ngaphandle komlo malunga nespekthi zokusebenza.

IiHiccups eziSebenzayo kunye neeNyaniso zoBonelelo

Ayisiyo yonke into ethe ngqo. Ukuhambelana sisilo. Ukufumana owona mthunzi weblue ukusuka kwibhetshi ukuya kwibhetshi, okanye nakwibhetshi enye, kulucelomngeni. Ukufunxwa kwedayi kuxhomekeke kukwahluka kwemizuzu kwikhemistry yokuhlamba i-passivation, ubushushu kunye nexesha. Ndiye ndathunyelwa apho ukuhluka kombala kwaphawuleka ngokwaneleyo kangangokuba umakhi wezakhiwo wakhaba kubo kwisicelo esibonakalayo se-facade. Kwafuneka sitye iindleko. Kwiinkqubo ezininzi zemizi-mveliso, utshintsho oluncinci lwe-hue alunamsebenzi, kodwa kuya kufuneka wazi ukunyamezela kwesicelo sakho kumahluko.

Enye i-hiccup kukumelana nokunxiba. Umaleko wechromate onedayi unokunganyangeki kancinane kwi-abrasion kunezinye ezityebileyo nezicacileyo. Ngexesha lofakelo ngezixhobo zamandla okanye ukuba ibholithi itsalwa ngomjelo wentsimbi, unokubona iimpawu zokukrwela ezibuthathaka ezibonisa i-zinc engaphantsi. Yinto yokuthambisa kuphela kwaye ayichaphazeli ukubola, kodwa yinto yosukuzwano kunye nabathengi abancinci. Ufunda ukucacisa ukuqiniswa kwesandla kwindibano yokugqibela okanye ukusebenzisa i-washers yokukhusela kwiindawo ezibonakalayo.

Kulapho ukusebenza nomenzi okhethekileyo kwenza umahluko. Inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., esekwe kwisiseko semveliso yenxalenye enkulu yaseTshayina eYongnian, inomthamo kunye nolawulo lwenkqubo yokulawula ezi ziguquko ngcono kunevenkile yomsebenzi omncinci. Indawo yabo kufuphi neendlela ezinkulu zothutho ezifana neBeijing-Guangzhou Railway kunye neBeijing-Shenzhen Expressway ayikho nje into yokuqhayisa; kuthetha ukuba zilungele ukuhambelana, umthamo omkhulu okhuphayo ozinzisa iinkqubo zeekhemikhali. Unokufumana indlela yabo yokugqiba okukhethekileyo okunje kwindawo yabo https //wwww.ziitasteners.com. Ayenzi nje iibholithi; balawula iibhafu zekhemistri kwinqanaba lemizi-mveliso, yiloo nto uyidingayo ukuhambelana kombala.

I-Case in Point: Uvavanyo olungaphumelelanga kunye neMpumelelo

Sakha sazama ukusebenzisa iibholiti ezimnyama ezifakwe i-zinc kwi-boardwalk railing system. I-spec ibize ukugqiba okumnyama kunye nokuchasana nokukhula okuphezulu. Safumana isampuli emnyama entle, efanayo. Kodwa kwiimvavanyo zokutshiza ityuwa (i-ASTM B117), i-coat emnyama ibonise iimveliso ezimhlophe ze-corrosion (i-zinc salts) ngokubonakalayo kwaye ngokukhawuleza kunomlingani oqhelekileyo we-zinc. Ukusebenza kwe-corrosion, ngamanani, kwakufana, kodwa ukusilela okubonakalayo kwakhawuleza. Umxhasi woyika kwiifoto, ecinga ukuba i-coating ayiphumelelanga ngokupheleleyo. Sifunde ukuba kwiindawo ezinobungozi kakhulu, ezibonakalayo eziphezulu, ukuthotywa kwe-aesthetic yeengubo ezinemibala kufuneka ibe yinxalenye yovavanyo, kungekhona nje i-rust endpoint. Ngamanye amaxesha, isambatho esincinci esibonakalayo lukhetho olulumkileyo.

Thelekisa oko ngempumelelo kulwakhiwo lwangaphakathi lweemodyuli. Inkampani eyakha amagumbi esibhedlele asetyenzisiweyo asebenzisa iibholithi ezinombala: orenji kwizixhaso zemibhobho yombane, ezibhlowu kwizibiyeli zegesi yezonyango, ezingwevu kumaqhina eludongeni. Bonke babe I-winc-ibhloko ngombala wechromate ofanelekileyo. Ngexesha lokwenziwa kwangaphandle kwendawo, abasebenzi banokuqinisekisa ngokukhawuleza ukuba babambe isiqhoboshi esifanelekileyo kwisibiyeli esifanelekileyo. Kwisiza, abahloli banokuqinisekisa iinkqubo ngokujonga nje. Iprimiyamu yeendleko zokuqala yahlaziywa ngeempazamo zendibano ezincitshisiweyo kunye nokufakwa ngokukhawuleza. Ukuphumelela kozinzo kwakusekusetyenzweni kwakhona okuncitshisiweyo, inkunkuma encinci yempahla evela kufakelo olungalunganga, kunye nohlengahlengiso olulula lwexesha elizayo ngenxa yokuba inkqubo yenziwe ngendlela ecacileyo.

Ke, Ngaba Yinyani Ngokwenene?

Ukuyibiza ngokuba yinto entsha etshintsha umhlaba, iya kuba yinto egqithileyo. Kukongezeleka, ukucokisa okuqhutywa sisicelo. I Ukuveliswa okuzinzileyo ileyibhile ifanelekile xa uqwalasela umjikelo wobomi bonke: amandla okusebenzisa iichromates ezinetyhefu encinci, ukuncitshiswa kwenkunkuma ngokuchongwa okuphuculweyo kunye nokugcinwa, kunye nobomi benkonzo eyandisiweyo ngokuqinisekisa ukuba isibophelelo esichanekileyo sisetyenziswa kwindawo echanekileyo ukusuka ekuqaleni.

Ayiyiyo yonke inkqubo. Ngobuninzi bezibophelelo ezingcwatywe ngaphakathi kumatshini okanye kwisakhiwo, yindleko engadingekile. Kodwa apho umbala wongeza umsebenzi-ukhuseleko, ukuchongwa, ulawulo lwenkqubo-ihamba ngaphaya kokuhlobisa. Iba sisixhobo sokusebenza kakuhle kunye nokuphila ixesha elide.

Isitshixo seenjineli kunye nabaxeli kukuhamba ngaphaya kutheni ndifuna ibholithi enemibala? ingqondo yokubuza ingaba umbala unokusombulula iindleko ezifihlakeleyo okanye umngcipheko kule ndibano? Nantso ke inguqu. Inxalenye encinci, kodwa njengoko nabani na kwimveliso uyazi, usathana, kwaye ngamanye amaxesha usindiso, lukwiinkcukacha. Itekhnoloji, njengaleyo ilolongwa ngabavelisi kwiihabhu ezifana neYongnian, ikhulile. Inguqulelo entsha ikwiingcinga zethu malunga nendlela yokuyisebenzisa.
